Discussion on power engineering and transmission line management measures?

With the continuous development of society, power engineering construction has become a basic project to continuously meet people's electricity demand. With the increasing demand for electricity, the number of power engineering construction projects is also increasing. Transmission line is an important line to ensure the tradition of electric power, and its construction quality is very important. Strengthening the construction management level of transmission lines in power engineering to ensure the construction quality of transmission lines has become the top priority of current power engineering construction.

1 analysis of construction technology of transmission lines

Transmission lines are the foundation of power grid construction. Mastering the construction technology of transmission lines comprehensively and adopting scientific and reasonable construction technology are conducive to improving the construction quality and progress and ensuring the safe operation of the power grid. The technologies involved in transmission line construction can be strengthened from three aspects according to different construction periods, namely, basic engineering construction technology, tower erection construction technology and post-maintenance technology. (1) foundation construction technology. China has a vast territory and complex geological conditions, and the erection of transmission lines is restricted by topography, geology and climate conditions. Therefore, the erection of transmission lines must be combined with local natural conditions to avoid the damage of large-scale excavation to the natural environment, and at the same time, it is necessary to maintain the stability of foundation projects and avoid the sinking and inclination of towers. Mainly involved in: ① pile foundation construction technology. Pile foundation construction mainly includes drilling and grouting. Before drilling, the position of the hole should be accurately positioned. Once the hole position deviation occurs, the hole should be swept to ensure the smooth pile burial in the later period. ② Excavation construction technology. Before excavation, data collection and equipment testing should be carried out on the hydrogeological conditions in the excavation area to ensure proper site selection. (2) Construction technology of tower assembly. In the process of transmission line construction, the tower is the most basic bearing body, and its stiffness, strength, structural form, grounding position and connection mode are closely related to the construction quality of the whole project. (1) The tower structure should be based on the actual geological conditions, transportation and power demand to determine whether to choose concrete poles or iron towers. In areas with convenient transportation and good geology, concrete poles are often used; Iron towers are often used in areas with inconvenient transportation and complex geological environment. Low-voltage lines generally choose concrete poles; High-voltage lines choose more iron towers. ② During the operation of overhead transmission lines, grounding resistance is an important index to measure the lightning protection level of transmission lines. The smaller the grounding resistance, the higher the lightning protection level of the line. ③ Transmission line stringing construction usually includes two major contents, namely, construction preparation and stringing operation. In the preparation work, the construction personnel must fully consider the wiring form and select the wiring form according to the specific needs of transmission line construction in power grid engineering. In the process of choosing the pay-off method, there are usually two ways, namely, tension pay-off and dragging. In the process of applying the latter, the power cord can be pushed forward by directly mopping the floor without braking at the sweeping coil. Therefore, in actual construction, although this method is convenient, serious friction will be formed between the power cord and the ground, which is easy to damage the power cord. More importantly, this method will reduce the construction efficiency. The tension pay-off method is usually used at voltages above 1 10kV. In the process of applying this method, there will be a certain tension between the ground wires, and there will be no serious friction between them because of keeping the distance. However, the diameter of the pay-off pulley should be larger, and only in this way can the wear of steel wire be minimized. (3) Line maintenance construction technology. After the transmission line is put into use, the relevant staff should regularly overhaul the line to eliminate hidden dangers. When an accident occurs, construction technicians should be organized to carry out emergency repair in time, and the line fault should be eliminated as soon as possible to ensure the production and living needs of the people in the line fault area.

2 transmission line construction management measures

(1) Construction quality control. Ensuring the construction quality of transmission lines is the core of transmission line construction. We can start from the following aspects: ① Construction design should be carried out on the basis of field investigation, and field construction should be effectively combined with construction design. (2) Strictly control the quality of transmission line construction materials. All building materials must be purchased in strict accordance with relevant specifications or standards, and can only enter the construction site after passing the quality inspection. (3) Improve the professional technical level of transmission line construction personnel, standardize their construction behavior, and dynamically manage the whole construction process to ensure that the construction quality and time limit meet the construction requirements. (2) Construction safety management and risk control. Safety management is a necessary prerequisite for transmission line construction. The construction and maintenance of transmission lines are high-risk operations, with frequent safety accidents, which seriously threaten the life safety of construction workers and social harmony and stability.

3 Conclusion

With the development of society, the power industry is developing rapidly and the demand for power is increasing, which makes the structure of power grid system and infrastructure increasingly complex. Optimizing the construction technology and management of transmission lines is conducive to further improving the power transmission capacity of transmission lines and providing reliable guarantee for people's production and living needs.
